WINDOW-=SCREEN.

SPECIFICATION forming part of Letters Patent No. 732,693, dated July7,1903.

Application filed March 5,1908.

To all whom it nuty concern:

Be it known that I, JOHN Q. ADAMS, a citi' zen of the United States,residing at James: town, in the county of Green, State of Ohio, haveinvented certain new and useful Improvements in Window-Screens; and I dohereby declare the following to bea full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to window-screens in general, and moreparticularly to the class of folding window-screens; and it has for itsobject to provide a construction which may be readily adjusted to theposition between a window sash and sill and which when secured in placecannot be removed from the outside of the window.

A further object of the invention is to provide a construction inwhichthe window-sash will be held against movement from position rearwardlyto draw the dowel-pins out of the sockets of the window-frame, thebottom rail of the sash being partly in section to show the sockettherein. Fig. 3 is a horizontal section through the screen in the planeof the upper dowel-pin. Fig. 1 is a section taken vertically through thecenter post of the screen and including the clamps or hooks thereof.

Referring now to the drawings, the present screen includes a center post5, of rectangular form, as illustrated, and to which are hinged tworectangular frames through the medium of hinges 6, so that said post andframes may lie with their corresponding faces fiush when their adjacentedges are in contact.

Each of the screen-frames includes two rectangular members 7 and 8,which are disposed to coincide,and the adjacent faces of each pair ofmembers are corrugated to more firml y Serial No. 146,395. (No mode];-

grip the steel wire-netting 9, wh ich is clamped therebetweeu, themembers being held in clamping positions by screws 10, engagedtherewith.

In the use ofthe screen it is disposed upon the outer lower portion ofthe window-sill 11, the outer edges of the screemframes lying betweenthe beads of the window-frame, so that the bottom rail 12 of the lowerwindow-sash may rest upon the upper edges of'th'e'screen frames and theupper end of the central post.

When putting the screen in place, thewindow-sash is raised toits limitand the'screenframes are brought together and are passed through thewindow outwardly-until thepost 5 stands beyond the sash.

The outer or vertical edges of the screen-frame are'then insertedbetween the corresponding beads of the wind ow-frame and the post isthen drawn inwardly, so as to spread the screen and force the edges ofthe frames firmly in to place, said frames being provided at theirvertical edges with the dowel-pins 13, which enter sockets 14 in thewindow-frame. This manipulation of the Window-screen is facilitated bythe handle 15, which isattached to the central portion of the inner faceof the post 5.

To prevent return or outward movement of the post 5, an angularspring-plate is provided including the vertical arm 16, which isattached to the inner face of the post 5 at a point slightly above itslower end, and the arm 17, which projects at right angles to the arm 15and the post, the arm 17, havinga longitudinal slot 18 therein at itsfree end portion. A second plate 19 is provided and has a hook 20 at oneend, the plate ,19 being connected with the arm 17 by means of thethumb-screw 21, which is passed through the slot 18 and engages theplate 19. By loosening the thumb-screw the plate 19 may be adjusted tomove its hook toward and away from the post 5, so that the hook may beengaged over the inner face of the sill whatever the width of the lattermay be within certain limit. Thus may the lower endof the post.

5 be held against outward movement.

At the upper end of the post 5 is a vertical pin 22, and in the bottomrail of the windowsash, which rests upon the screen, is a socket 23,which receives the pin to hold the upper end of the post 5 firmlyagainst displacement.

To prevent the window-sash from being thewindow, a spring-plate 24 isprovided and is pivoted to the inner face of the upper end portion ofthe post 5, the free end of this spring-plate being provided with apointed hook 25, which may be engaged inthe bottom rail of the sash orover the upper face of the latter, as may be preferred, so that theupward movement of the sash would tend to carry the screen with it, andas the screen is held against upward movement by engagement of itslaterally-directed dowel-pins in the sockets of the window-frame thewindowsash cannot be moved upwardly. The upper and lower plates securedto the post 5 are of spring metal, so that the lower plate may be raisedto carry its hook above the sill before the post is shifted outwardly,and the upper plate may be drawn inwardly to move its hook over thebottom rail of the sash before it is swung pivotally. With thisconstruction it will be seen that the screen may be easily and quicklyput in place and as readily removed, and that when in place it cannot heremoved from the outside, while by forming the wire fabric of steel wirethe noise incident to cutting of the fabric would be so great as toattract the attention of a person or awaken a sleeper.

In practice modifications of the specific construction shown may be madeand any suitable materials and proportions may be used for the variousparts without departing from the spirit of the invention.

What is claimed is- 1. A window-screen comprising a central post havingmeans at its extremities for engagement with the sill and sash of awindow respectively and screen-frames hinged to the central post.

2. A screen comprising a central post having means at its ends forengagement with a window sash and sill respectively, and screenframeshinged to the post and having pins at their side edges to engage thewindow-frame.

3. A window-screen comprising a central post and frames hinged to thepost, and means carried by the post and frames respectively forengagement with the sash and frame of a window.

4. A window-screen comprising a central post having an extensiblehook-plate at its lower end for engagement over a window-sill and havinga pivoted hooleplate at its upper end for engagement with a window-sash,and screen-frames hinged to the post and having means at their sideedges for engagement with a window-frame.

5. A window-screen comprising a central post having a pin atits upperend for engagement with a window-sash and having hookplates at its upperand lower ends for engagement respectively with a window sill and.window-sash, and screen-frames hinged to the post and having pins attheir outer edges for engagement with a Window-frame.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN Q. ADAMS.
